Abstract
An example apparatus includes: a first switch; second and third switches coupled in series; a driver configured to: receive a first control signal; provide a second control signal having an edge having a first slope to control terminals of the first and second switches based on the first control signal; and provide a third control signal having a second edge having a second slope to a control terminal of the third switch based on the first control signal, the second slope being higher than the first slope.
Claims22
An apparatus comprising:
- a driver including:
- a first inverter having an input and an output;
- and
- a second inverter having an input and an output, the input of the second inverter coupled to the output of the first inverter;
- a first transistor of a first type, the first transistor having a first current path terminal, a second current path terminal, and a control terminal, the control terminal of the first transistor coupled to the output of the second inverter;
- a second transistor of the first type, the second transistor having a first current path terminal, a second current path terminal, and a control terminal, the control terminal of the second transistor coupled to the output of the second inverter and the control terminal of the first transistor, the second current path terminal of the second transistor coupled to the second current path terminal of the first transistor;
- and
- a third transistor of the first type, the third transistor having a control terminal and a first current path terminal, the control terminal of the first transistor coupled to the output of the first inverter and the input of the second inverter, the first current path terminal of the third transistor coupled to the first current path terminal of the second transistor.
